39mm offset? with 7 inch wide wheels, the 45 series is too fat. I've figured it out finally.

17X7 will rub with 215's unless your offset is 42mm or greater. Don't try 215/40, that's stupid. 215/45 is min.

17X7.5 will rub if you're 225/45's, BUT WON't with 235/40's, nor with 215/45's with ANY offset (since the extra .5inches stretches the tire out).

I haven't compiled my 18incher list yet. This should be part of the FAQ.

Isneo, write us a code: Will I rub with ___________
(Run fancy ssmumich00 algorithm) , and you stand good chance or probably not (like a magic 8 ball). . .




Still not all true. I never rubbed with my RS5's (17x7, 40mm) or my Attacks (17x7.5, 45mm) and I used the same 215/45 tire on both.
